Volcan Maderas

Volcan Maderas is a 15.3 kilometer moderately trafficked loop trail located near Jinotega, Rivas, Nicaragua that features a lake and is rated as difficult. The trail is primarily used for hiking, walking, nature trips, and birding and is accessible year-round.

Much more difficult than the alltrails review. Definitely worth the challenge but don't be fooled, it's hard as hell. Mostly mud and monkey climbing so just be prepared, the way you go up is the same way back down. People with knee trouble might struggle.
